Per Sjöborg has a series of audio interviews with leading researchers and thinkers in the field self-reconfiguring modular robotics.

On his website Flexibility Envelope he describes the field of self-reconfiguring modular robotics as the joining two elements:

The first part is Modular robotics. This is a branch of robotics that aims to build complex systems with simple components. A bit like Lego,simple pieces are,by cooperating,capable of building complex objects.

The Second part is Self-reorganization to make the units able to move among each other on their own accord and thus reconfigure themselves from one task to another without human intervention. This also allows the system created to be active and dynamic.

His audio interviews can be found on here and are a great listen.
